THE PRODUCT


RTLS, WSN and IoT: Problem Statement

• RTLS and location aware IoT and WSN have a fantastic

market potential through a myriad of applications.

• However this is today a fragmented market as current

technology limitations do not allow large scale adoption.

• The problems with the existing solutions and restrictions on

mass adoption are:

• Location precision

• Power consumption

• Price

• Interference and multi-path

• Environment dependent tailor-made systems

• DecaWave Solves all The Above Problems

Ultra Wideband with Reflections

Particular method of radio transmission using narrow pulses with very attractive benefits

UWB allows very high precision measurement of the time of flight of the signal


Why Ultra-Wide Band (IR-UWB)

Ability to very precisely measure the time of flight of the radio signal from

transmitter to receiver => very accurate distance measurements (range &

precision) – orders of magnitude more precise than existing systems

Time

ScenSor: Standard Compliant at Best Price, Best Power, Right Now

Why is ScenSor better

- Smaller Silicon Implementation hence cheaper and lower power

- Operates using up to 12 times lower energy in transmit & 7 times lower energy in receive than

competing narrowband solutions

- Can locate items within 10 cm of where they are, and highly reliable

- LOS approx. 300m, NLOS 35m, allowing it to be deployed in WLAN APs

- Can identify up to 11,000 items within a 20 meter radius

- Both One way and Two way ranging capability, hence no infrastructure required

- Very high immunity to multi path fading, allowing east installation for end user

- Avoids spectral crowding of the ISM bands, hence dove tailing with WiFi installations

DecaWave solves the problem of location specific identity indoors at

ultra low cost & ultra low power

DecaWave Launches Industry’s Most Precise Indoor Location and Communication

Decawave DW1000 Launch

DecaWave Launches Industry’s Most Precise Indoor Location and Communication CMOS Chip

Provides +/-10cm precision with ultra-low power, enabling new RTLS applications

Dublin, Ireland. - November 7, 2013 - Fabless semiconductor company DecaWave announced today its first single chip of the ScenSor wireless technology family DW1000, which makes indoor location and communications more accurate, cost-effective and power-efficient than ever before. This is the first Integrated Circuit on the market to electronically identify the specific distance to any object, person or thing with +/-10cm precision. With multiple patents, DecaWave’s ScenSor works by transmitting wireless signals to readers that use them to locate the tagged object to within 10cm. The chip is the smallest device of its class, is compliant with IEEE 802.15.4a standards (now IEEE802.15.4-2011), and uses ultra-low power - it can operate several years from a battery cell or within an energy harvesting environment. These features make the chip functionally and economically viable to deploy, both in volume and in remote locations. ScenSor can either replace or complement the Radio Frequency Identification (RFID) and WiFi technology currently used for indoor tracking (where GPS signals are unavailable) by allowing for more specific, minute-to-minute location information for high-value goods over short range and through obstructions providing more accuracy than ever before. This brings new opportunities across multiple industries including future applications for the technology incorporated in smartphones and tablets. “Until now, 10cm location communications across close distances was not possible and current systems with meter-level accuracy have limited reliability, signals would be lost and there was a high risk for error. Customers ask for more than average accuracy most of the time. Our new ScenSor chip changes all that, it provides unprecedented accuracy all the time” said Ciaran Connell, CEO at DecaWave. “More than 1,800 firms and institutes have expressed interest in implementing our technology for applications such as factory and building automation, agriculture, healthcare, ePOS and retail, and warehousing. We’ve created a foundation for all locator systems, and the systems can now be tailored to specific applications and environments.” About DecaWave DecaWave is a pioneering fabless semiconductor company developing a family of integrated circuit products called ScenSor , compliant to the IEEE802.15.4a standard, which can electrically identify the specific location of any object, person or thing in an indoor environment at very competitive cost, ultra-low power and with a required level of precision never achieved before +/-10cm. With applications in diverse markets including factory and building automation, agriculture, healthcare, ePOS and retail, and warehousing, the company’s flagship DW1000 chip has garnered interest from more than 1,800 firms, research centers and individuals. DecaWave is headquartered in Dublin Ireland, with offices in France, South Korea and Taiwan, and will open a US office early next year. www.decawave.com

TDOA RTLS: Decawave demo

• This demo is based on a TDOA scheme with 4 anchors and 1 or 2 tags

– Each Tag blinks on a regular basis

– The Anchors receive the Tag signal and the location engine calculates the Time

Difference of Arrival and estimates the Tag location.

– The location Engine runs on a PC

• The 4 anchors are using a wireless synchronization algorithm to eliminate

the clock offset error.

– One Master Anchor sends the reference clock to the other anchors in range
